Lignin accounts for 30 percent of all non-fossil organic carbon on earth. And can be used as an environmentally friendly alternative to many petroleum-derived substances.
After cellulose, lignin is the second most abundant biopolymer on earth. It is a 3D complex molecule built up from phenolic alcohols, known as nature’s glue. About 100 million tons are produced worldwide as by-product of wood pulping mills and biorefinery set-ups. There are two principal categories of lignin: sulphur-containing and sulphur-free.
Protobind® products are well known and have been widely used in research and development by institutes, universities and companies and are commercially used in a variety of applications.
Sulphur free soda lignin
Protobind 1000 is a sulphur free lignin generated from soda pulping of annual fibres such as wheat straw and is available as a dry powder product with low ash and sugars impurities.
Since the product is renewable, its production cost is to some extent independent from the price volatility of oil and as shown by EMPA has a substantial potential to reduce greenhouse gas reduction.

Our focus areas
The gut is far more than a digestive organ. It’s a complex ecosystem intertwined with immunity, energy metabolism and mental clarity. With up to 70 % of the immune system located there, gut balance is foundational to overall health. Our current research focuses on lignin-derived compounds that support beneficial microbes, moderate inflammation and fortify the gut barrier.
Through rigorous clinical validation and advanced formulation we translate lignin’s bioactive power into safe, effective solutions. From nutraceuticals to future medical or functional applications, enabling the body to defend and restore itself from within.

Gut Health
Experience
An unstable gut may present in many ways: bloating, fatigue, food sensitivities, poor focus or frequent infections. These may appear separate, but they’re often connected signals from the body’s inner ecosystem. Siranius solutions work to restore balance.
Effect
Our lignin-based formulations aim to reduce inflammation, harmonise the microbiome and enhance natural defence mechanisms. The outcome is tangible: a calmer gut, clearer energy, and greater everyday resilience.
